DVD formats

I am trying to get a 1-hour interview on a DVD. So far, the first 30 minutes is a 23G file in mp2. If I re-render in mp4 (to reduce file size), will the quality be comparable to 50g of mp2 compressed to 4.7G for the DVD? Does dual-pass add much to the file size? Would VBR reduce it a bit? I've seen various opinions on this. I'm using Vegas.

Thank you,

Don

No idea what you are doing but those files sizes are crazy.

If you have an hour and encode at 7 Mbps it will not even fill up the disc. Make sure the audio is encoded as ac3.

NEVER go to mp4 waste of time and quality. DVD is always (and only) mpeg2 (m2v)

Export that big file out of FCP or Quicktime Pro as DV NTSC with the sound at 48mhz, should be a preset for that. That should bust it down to a few gigs, then pull it into DSP4. No AIF, use AC-3 audio. That should look just fine and fit quite easily.
